2 General Description The VC7300-series is a highly integrated wireless MCU which is a perfect fit to IoT networking and sensing applications. It integrates Cortex-M3 MCU, 512/1024 KB Flash, 128 KB SRAM, sub-ghz radio and other functionalities such as UART/SPI/I 2 C, WDT and Timer, etc. The VC7300-series has varieties of power saving modes which can be leveraged to build ultra-low power IoT networks with powerful computing capability. The embedded sub-ghz RF transceiver features low power consumption, longrange and robust wireless links, being able to reject large nearby interfering RF signals. Key Features ARM Cortex M3 CPU core with 512/1024 kb flash and 128 kb RAM Best-in-class RF performance with VC7000 sub-ghz RF transceiver AES accelerator of 128/192/256-bit keys Ultra-low power wireless SoC RX mode: 18 ma TX mode: 45 ma@+13 dbm 110 ma@+20 dbm Sleep mode: 2 ua Deep sleep mode: 1.1 ua AES accelerator of 128/192/256-bit keys MCU Features MCU 32-bit Cortex M3 with maximum MHz operation speed Single cycle multiplier Standard 2-wires SWD debug interface 512 KB Flash with write protect, support both IAP and ISP 128 KB SRAM with parity check and data retention under sleep mode 16 KB SRAM with data retention under deep-sleep mode Support abort exception detection including Flash check-sum error, SRAM parity error, memory address error and memory align error
